- MJM. John1 day ago5.0The place is clearly well managed and I can see there are standards. I also appreciate the greetings and the smiles. Only 1 nitpick, I personally don’t like it when servers memorize orders. It only makes customers nervous you’re going to forget our requests (especially when allergies are involved), and in my experience that’s what often happens especially when we see you go memorize another party’s order before finishing placing ours. It doesn’t help or impress anyone. Please just write it down. Other than that our meal was great and I’ll definitely be coming back. Thank you.
- LFLexi Finkle2 days ago5.0This place was EXCELLENT. We were in town due to some unfortunate circumstances and in search of good seafood to lighten the experience. This restaurant was recommended and it did not disappoint. Every employee, from the hosts to the busboys were smiling, friendly and welcoming. Had the crab cakes and the halibut, and both agreed that these were the best either of us has ever had. EVER. Imagine my surprise to learn that this is a chain!
- MWmonica wilson4 days ago5.0Went for happy hour after work w my friend. Marielle was our server she was so kind and gave great service! I’ve never been but her and Josh did an excellent job making us feel welcomed and taken care of. 10/10 will recommend :)
- AAAnithaJul 18, 20263.0The service was a bit meh. The servers looked young and inexperienced. We never were asked if we needed anything else after we got our drinks- no refills on waters or anything else to drink. Food took a while to come out and my hanger steak was a bit salty and oily. My husband ordered a burger and it came with no sauces, lettuce or tomato- so he essentially had to ask for it all and build his own- very strange because he didn't order it that way.
- SLStephen LavenderJul 10, 20265.0Can’t believe this place is a chain restaurant. The food was absolutely excellent. Crab cakes, smoked salmon, ceviche, deviled eggs, fish tacos, and fritters were all raved about at our table of 18. In an area with lots of restaurants, Coastal Flats stand alone. We’ve been to this area many times over the years for lacrosse tournaments and this place is simply the best. We even had a small issue with a missed order and they made up for it in spades.the manager Karlein and server Ricky are best in class. Take the extra walk from the hotel around the lake. It’s worth it.
