Outstanding food. Had the chicken tetrazzini casserole, Italian penne pasta and dessert tray for a family gathering. Wow- just wow - I’ve never been a tetrazzini girl - I am now - can’t wait to try all their dishes.

I love the family feel - walking right into the kitchen and picking up the food! Love it.

The management and staff could not be kinder - customer service at its finest. They know what they’re doing!

Thank...

Love this place! My favorite sandwich is the Sassafras.Its delicious.
I just wish the portion sizes made more sense for the high prices. I’m totally fine with paying more for good, well-portioned food, but the sandwiches and sides feel a bit underwhelming for what they cost. :( My mac and cheese side, which I pay an extra $3 for, was only half full, and a very small cup. Pretty disappointing. If the portion sizes better reflected the pricing, I’d honestly eat here...

We love square onion! Unfortunately most of the staff comes off very annoyed and as we were bothering them . Multiple different employees were very rude and standoffish.

Unfortunately with being on the more expensive side and usually loving the food this was disappointing for myself and family
