I think Basic 4 was one of the most disappointing veg restaurant experiences I've ever had. I ordered the "Carrot Tuna", which a previous user, BevyBev, raved about. Big mistake. Considering that this user only has one review on VegGuide.org, I can't help but wonder if he/she is an employee/owner of Basic 4 and posted this false review to boost business.
I've had tofu, seitan, and chickpea-based "tuna" and they've all been good. Some use dulse/seaweed to give it a "fishy" taste, some use chopped celery to give it better texture, and all use some sort of vegan mayo. Basic 4's "carrot tuna" uses none and they don't add anything else to give it interesting flavor or texture. The sandwich was literally carrots on a pita. The pate appeared to be pure carrots pulverized in a food processor, with a little onion and maybe salt and lemon juice. How on earth is this supposed to resemble tuna? The plain carrot mixture was scooped into a pita bread with lettuce, onions, and tomatoes - no protein, and no mayo or sauce. It was the most boring sandwich I've ever had and a total waste of $6. I couldn't bring myself to finish it, so I took half of it home, added a veggie burger, some Veganaise and Siracha, and called it a day.
I also ordered the cream of broccoli soup for about $5, which turned out to be very bland. I'm glad they offered a vegan cream soup, as much of their menu isn't vegan (it looks like some of the soy meats they use contain milk), but it tasted like the stereotypical vegan soup that you would NOT want your non-vegan friends to taste. There was no robust flavor so instead of using rich vegetable broth, soy cream, and vegan butter, I think they just used water and thickened it with flour. No good.
