Just got back from a lunch at the Walnut Grill. I had been there once before about 3 years ago. I don't remember much other than it was a solid meal and the mushroom soup I got was good.
Anyway, it was fairly empty for lunch. Perhaps it's because it has a darker atmosphere (today was gorgeous out) than other SS places. I had the lunch special which was a Cajun chicken sandwich with mozzarella, basil and roasted red peppers (9$). GF got the veggie sandwich which has portabellos, spinach, feta and onions (9$).
My sandwich was great. The chicken was nicely cooked (not dry). The mozzarella was nice and big. The basil was a nice touch and fresh. The roasted red peppers were from a can, but were good. Served on warm ciabatta. Sandwich wasn't overly salty either. The fries were surprisingly good.
GF's veggie sandwich was equally good. I usually don't like spinach, but the bite I had was nice and feta/mushroom-y. She ate all of it (which rarely happens).
I also got a Proper draft which is an English Pale Ale. It was quite good. Nice and malty with minimal hops.
