We sat in the bar at a booth and ordered drinks and heavy appetizers.
The happy hour prices are pretty reasonable and everything was delicious
Our sever Nicole was OUTSTANDING
The atmosphere is quiet and cozy. The staff is friendly and accommodating. The food is excellent, but a bit pricey. Be prepared to spend some money.
The chairs need to updated. Carpet was stretched. Ceiling in need or repair.
I hadn't been there in awhile. I had a friend give me a gift card for Xmas so wife and I had dinner there last night. Everything was really great service and food.. I'm handicapped and the entire staff took excellent care of me. Definitely going back!
We had an amazing first time experience, however we were not impressed with the rib eye steak due to it not being made medium rare as we order. Had to send it back twice unfortunately. The shrimp and scallop plate was truly amazing! We will be going back for sure. The wait staff was exceptional.
Great waiter Ed who makes the dining experience fun.
Absolutely one of our favorite places. The best staff ever. Super friendly and professional.
Seated right away, served very quickly, apps and salad out quickly and dinner served shortly after. Prime Rib was fantastic, shrimp cocktail cold and tender..
The food was amazing! The only thing we were caught off guard by was the cost of the old fashions- $25 each! If not for that it would have been perfect.
Historic restaurant. Beautiful setting, caring and attentive service. Food was very good. I recommend it!
Good food and great wine selection
It was for a birthday party. Great atmosphere.
Had a great time. Food and service were great. One of the best spots in Rancho Cucamonga.
The food was very good as always and the Sycamore has gotten better over the years as it became a prime steak house with many fine non steak entrees. We keep coming back.
Get to the Sycamore Inn!
Bourbon Old Fashioned and Josh Cabernet. For appetizers, started off with the crab cakes and the stuffed mushrooms….perfect.
For entree it was the large prime rib and the rib chop. Both meats were cooked and seasoned to perfection. In fact, the rib chop is the nest I have ever had. The sides were creamed spinach and the potatoes.
Another set of drinks for dessert tonight!
You must ask for Ed as your server…professionalism, warmth and the best server we have ever had.
Get to the Sycamore Inn.
Loved the atmosphere. Servers very attentive. For the price I was expecting the food to be delicious and sad to say it was nothing spectacular. Totally let down. My family and I were disappointed and unfortunately won’t be back.
Anniversary dinner.. I would like to try the main dining room next time.
We were last here a long time ago. This was a totally different experience. The lower level was depressing. The service was mediocer, and the food was nothing special.
We dined at the restaurant for my wife's birthday dinner. As usual, it was a great experience. Waiter and all staff were very pleasant and attentive. The food was delicious and cooked as ordered.
We were heading to Women’s night of Worship at our church, Hillside and ate at Sycamore first. It was wonderful!
Food and service was incredible! Yes it is pricey, but for a special occasion it is definitely a great choice.
Amazing Fanny bar oysters!
A sad day in what was one of my favorite places... I thought I had made reservations in the regular indoor dining area behind the bar; to my surprise, we were place in a dungeon under their main floor that you get to through an outside set of stairs.; where they have accommodated tables and chairs, you may find in a conference room... We decided to make to best out of it, since we were celebrating my daughter's in law recent success... The appetizers were decent, and as expected, the entries, 2 were satisfied and 2 were not, the fillet mignon plate was very poor, and the prime ribe, lack flavor... then I had order a martini, nit; got a a dirty one, refused it, they brought me a drink on a regular glass, went to management for them to change, no apologies, no interest on neither waiter or management on my discomfort... the room was noise and bugs were flying around our food, because they left the door open to the outside... Sadly my last visit to what had always been an icon for me... I will take my $300 somewhere else next time...
Love the sycamore inn...! Being going to the sycamore inn for years...never had a bad experience...
Excellent early Mother’s Day dinner! We love the Sycamore Inn!
Celebrated our 21st Wedding Anniversary, the food, service and staff were amazing. They also mentioned our special event on their billboard for all to see, awesome time
Really expensive for everything being just OK.
Service: waitress and assistant waiter were both nice, but we had to ask for water, silverware, napkins, plates for appetizers, etc. They apologized when we asked and said they thought they had brought them.
Steak: underseasoned and tough... no way it was prime like it said on the menu
Scallops and shrimp entree: DELICIOUS!
Brussel sprouts side: meh... no seasoning
Mushrooms side: Very good!
Artichoke dip appetizer: So good! But they charge $2 for extra pita chips. And you're going to need more pita chips.
Oysters appetizer: So good!!
Drinks: we ordered martinis and red wine. Both were good!
A little unhappy mentioned a special dinner for anniversary and it was not acknowledged.
Ordered the porterhouse and it was a bit dry service took forever we got there at 6:45 we didn’t actually eat until 8pm! Service took forever one of the waiters was just rude every single time not worth the money
Worst experience I’ve ever had with a steak restaurant. Waiter could care less about whether we were there or not the Sycamore inn is known for their prime rib worst prime rib I’ve ever had. $900 later don’t waste your time
Service was awesome very clean happy hour is amazing
Your food was excellent, service was very slow and spotty but our waitress was very nice.
They asked us if it was a special occasion and I booked it on open table as a special occasion and then they never celebrated my wife’s birthday so we just paid and left don’t know if we’ll go back...
I was so disappointed. The first time we dined at this restaurant was on the main dining level. The service was impeccable the food was amazing and I couldn’t wait to bring our friends back for a second round. This time though we were sat in the lower level where it looks like you’re in a banquet room. The service was lacking (no bread plates, empty water glasses, too many times looking for our waiter to count) Unfortunately, the steak was undercooked and the wonderful night with our friends under delivered. We will for sure be back and hopefully the third times a charm
An excellent experience as a first time customer. Will be back again soon.
Food was good but for the expense I would have expected much better. The prime rib, while fine was lacking in flavor. Appetizer, filet mignon, and dessert were very good. Overall the experience was not on par with the cost.
Great historic building, wonderful professional service, excellent food, but very expensive.
The food was excellent. The restaurant was very nice, but the prices were very expensive. I think when you order steak dinners, it should come with sides, instead of having to order them separately.
Wonderful service. We had a reservation and were seated right away. Food was delicious
