A great establishment. Have been going there for 15 years and it is still great.

The usual excellent service and food

The food is good but not exceptional.
The sommelier was incredibly rude and aggressive.
Avoid.

Food really left a lot to be desired. Wine was good as was service.

The ambiance as always was excellent as well as the service.
My one disappointment was the quality of our steaks which were over seasoned with salt ands slightly over cooked.
What we really appreciated was our waitress accepting that feed back and offering to give us desert for free.
I love the guinea and will be back and appreciate the service but I think the kitchen was under too much pressure on this occasion.

See you soon.

Booked breakfast a week or so beforehand. Got telephone call at 1142 the evening before the booking to be told the Guinea does not do breakfast - bad service.

Great food, excellent service. Perfect Sunday lunch.

Excellent food and top-notch service

Nice night

As ever a great time with excellent service. I will be going back soon.

Superb food as ever at my most recent visit. A lively buzz is a great accompaniment to a business lunch and whilst you would not visit if "on a budget", the quality is always high. Sometimes you really do get what you pay for.

Excellent service and seating. Food was superb, must be in competition for best steak in London

Our steak took forever to arrive and then was just not that nice it tasted as if it had been grilled on an electric grill, on the positive side spinach with gruyere was a success

Never disappoints - great steaks, selection of wines, and service. The next visit can't come soon enough.

I eat regularly at the Guinea and it never fails to disappoint. Great meat and good staff.

Excellent meal and service

Very small room, lovely really but a bit too cramped. Food was excellent. Our first meal in London...excellent choice for high end English pub food! A carnivores delight!!

Staff were excellent, especially guy manning the door who managed to get me a pint while I waited for my guest and then sorted me out a great table.
Cote de Beouf was excellent and so big two of us couldn’t eat it.

Wonderful meal—an incredible Sunday roast beef, Yorkies, and veggies.

We went for the Sunday roast and selected the fillet and the T-bone steak with all the trimmings and sides. The steaks are well seasoned and the sauces also flavoursome. The tables are a little too close together which leaves little room for privacy. However, it is a popular spot so they have to make the most of the space. The pub is also a lovely place for a drink, especially in the summer as it looks out to the courtyard.

Superb experience in a real old school London classic

Food is good. But very small portions - we paid something like £6 for a broccoli side but there were only 5 small stem pieces!

Great steak restaurant and the pies are pretty immense. Really enjoyed this old school London pub dining experience. The quality and variety of meat options is really good.

The Guinea Grill is probably one of the most historical gastropubs I've been to. Built in 1423 as an inn and then transformed into a restaurant in 1953. Decor is still very dated, almost kept to it's old school setting with it's numerous of old paintings lined across the wall and an old green banquette below it in which we were seated. All the tables and seats were tightly put together, quite cosy. We were even greeted by a nice gentleman wearing a Victorian green tailcoat. Service was great throughout.

Sadly food was pretty average apart from everything cooked on the grill. We started on Eggs Royale which was okay. Salmon was a little too salty for my liking though and muffin a little dense.

Then we move onto our lamb grill, which was almost a breakfast dish, containing all the usual breakfast items along with one lamb chop, a lamb rib and lamb kidneys. There was definitely no effort on presentation, everything slabbed on our plate. For £26 it was very pricey for the portion, half of one mushroom, one tomato, a small sausage and egg. I do wish we got more of the lamb rib and lamb chop as they were delicious. Both of them grilled to perfection, butter knife tender with a great bite. Everything else was the standard affair.
We were quite disappointed with the pork belly roast. Although the trimmings were lovely, a nice giant fluffy Yorkshire pudding, fluffy roast potatoes, nice roasted veg and freshly steamed kale, we were in it for the pork. Sadly that itself was quite dry and boring and needed the gravy for it to be moist enough to enjoy.
We also ordered a side of beef dripping chips. Now these were good, chunky, fluffy and packed full of flavour. A must order.
I do believe all the ingredients were to the highest of standards but just wasn't executed to their fullest potential. Saying that, it was nice to experience an old traditional pub restaurant.

As always a great lunch superb wine and fabulous service

Loved it - the steak was cooked perfectly and the hospitality is great! Highly recommended.

Great spot but was a bit disappointed with the pie. It was an individual one but was very dry. The old style way of serving from a huge tray seems to have changed sadly.

The steak was surprisingly good and the prices are very fair for Mayfair/Marylebone

Fantastic meal at the Guinea as always. One of my favourites. Was seated upstairs which was initially disappointing but the room was full in 20 minutes and it is actually a very pleasant room.
Will be back for more!

Dickensian gem in the centre of Mayfair, great steaks and pies, attentive service at the back of a well frequented public house, with proper beer and IPA. It’s not cheap, but feels historic, go if you feel flush.

Returned here after a few years away. Very pleased to see it has not lost any of its character and food and service was exceptional.

Food great but, at these prices, having a mere 6 inch gap between tables is ridiculous. Conversation is virtually impossible - the noise being the only thing that aids any confidentiality......that is, unless you speak loud enough to be heard by your companion!

Always a good steak done the correct way. Don’t expect to have an intimate or business discussion because the tables are pretty close, but at least you can “sample” what others are having.

They have an interesting serving system with multiple hand-offs which seem a little strange for a smaller place, but it seems to work-don’t expect to make a new friend. But we go for the steaks and the sides don’t disappoint either. Everyone I have taken there always comes away with “that was one of the best steaks I have ever eaten in London” quote.

Amazing Sunday lunch

Excellent food and service. Wonderful wine to accompany.
Old fashioned service such a pleasant change. Will be back very soon.

Great pies but the format has changed in recent years as they are now served in a dish so its only pastry on the top and not the sides . Maybe for health reason that makes sense. Wonderful ale house.

Super place , lots of charm with a fantastic original pub and small rear restaurant which has a lovely buzz. Traditional but well cooked and very good feeling about the place . In a news just off Berkeley square with lots of space to stand out side in good weather.

Second visit. This time we were very squashed up having asked for a specific table which I later noticed was empty. I also asked for extra potatoes and fewer parsnips. I got three potatoes and a huge plate of parsnips. The wine was vastly overcharged. These issues got sorted out but I needed to complain first. It's expensive for a Sunday roast but worth it when they do it properly but this time they didn't. This was many due to poor service.

I love the Guinea, I must have been 10 times, they have the best steaks and pies that you could wish for. Great beers and wine selection and very knowledgeable staff.

I do wish they would improve the gent’s toilet, it is not fitting for such a nice place.

Everything was excellent. You get what you pay for - so not a “bargain” but wonderful steak at appropriate price.

The Guinea Grill is a lovely place for Sunday Lunch. Seating is a bit tight but the service was good and food lovely. A bit pricey, but it is in Mayfair-so to be expected.
