Here is a shameless revelstyle promotion, but here goes:
Check out the Red Herring Vegetarian Restaurant!
All entrees are $5 max, and they have un-freakin'-believable coffee for a dollar. They also have good hot treats for cold days coming up.
Also...for the regulars, the Herring is in danger of closing if they don't get more business. So don't let this fish go belly-up and try it out sometime. I've been there a ton of times, and they never disappoint. I'm not vegetarian or vegan, but it's good stuff (makes me consider going veg at times!). It's in the Channing Murray Foundation on Oregon Street in Urbana. And they have really funky painted walls and bathrooms too. So check it out!
