Best word to sum up my experience with Moxie's is mediocre.
For the price you pay, there are definitely better options available, you just gotta do some digging, but that's why you're on here, right?
The portions are quite generous for the price you pay on items like fish tacos or the salads. The chicken Madeira rigatoni is actually quite good and you can make it vegetarian by subbing with soy protein. Be warned, you will need to take a nap afterwards.
Service was slow, it didn't look like they were understaffed and the restaurant wasn't overly full so the hold up might have been in the kitchen.
Also if you're driving in, paid parking is $6/hour underground.
