I was a bit nervous about this place as most of the vegetarian items are not vegan and the dairy-free items are meat! I asked the girl at the counter if she could make anything vegan that's not on the menu and she turned out to be a chef that informed me of all sorts of vegan offerings. Apparently Ruggles Green is in the process of revamping it's menu.
This location (and perhaps the other) offers vegan Daiya cheese for the pizza but they only had cheddar (usually have mozz) when I visited so I skipped the pizza. I decided on getting tofu tacos instead of fish tacos (tofu isn't listed as an option on the menu), and got it without one of the sauces w/ milk in it. Since I was skipping a sauce, the lady told me I could have sliced avocado on the tacos for no additional charge - excellent! I can't say the tacos were the most fantastic I've ever had in my life (the tofu was slightly bland and came in one large chunk, vs smaller pan-fried chunks), but they were colorful, tasty, and I really appreciated the lady going out of her way to make me happy.
I dined with a meat-eating friend that has very little experience with vegetarian food and he got the veggie burger and fries and was blown away. I tried a piece of his veggie burger (a homemade nut/bean burger) and it was great. Unfortunately (for me, at least!), he got cheese on it so I couldn't really dive into it!
I think my favorite part of the restaurant is the self-serve free pickle and garlic station! I got a small cup of each and could have easily sat there eating pickled garlic all day.
