I tried Better Burger on 8th and 19th tonight. The beef burger was very tasty and reasonable at 4.95. Their condiments were especially good, and everything tasted fresh. I was a little wary of the whole slicked-out fast food phenomenon, but this was a very good, beefy burger.
Definitely a good option for cheap eats in Chelsea. I've heard mixed things about their vegetarian options, but as I haven't tried any I can't comment on them.
Anyone else try this place yet?
