Viva is a small pizza joint serving eight or nine different types of vegan pizza by the slice, as well as some traditional vegetarian options. It's a good place to get a quick bite in the East Village.
I had a slice of their vegan seitan-artichoke-sundried tomato pizza which came on a spelt crust ($6). The slice tasted okay, but wasn't great in my opinion. For one thing, none of the vegetables or the sauce seemed to have much flavor, and they also reheated the slice for too long, making the crust way to crispy (I like my crust to be softer or chewier, but definitely without "crunch" factor). Lastly, $6 is a lot to pay for a slice of pizza, vegan or otherwise (their cheapest option seemed to be a Daiya cheese slice for $3.25).
I also got a tiramisu-like thing for dessert ($4). I didn't realize Vegan Treats makes tiramisu, and damn was this good---easily the best I've ever had.
Viva has a few tables for two and some counter seating as well. It's a grimy place that always feel sticky (the front door is always slightly ajar as well), so it's not the type of place you want to have a sit-down meal per se.
While I love that Viva has whole wheat and spelt crusts, as well as a good array of vegan toppings (seitan, mock sausage, Daiya cheese), they need to keep their pizzas fresher somehow as they sit out all day and lose flavor. They also need to clean the place a bit better and make it a little more comfortable for an eat-in meal.
