Yuck. Normally I like to try a place a couple times before writing a review but I will not be getting anything else from this place.
My girlfriend's coworkers got take-out from here and she got a burger and a sandwich for me. Her burger had avocado, lettuce, and tomato. My sandwich was an ALT - avocado lettuce tomato on white bread. So there was similarity.
When we got it, the paper around both sandwiches was soaked through in grease and translucent. This is not, in fact, necessarily a negative. I didn't get food from a burger place to eat healthy. I love seeing the grease on the wrapping paper from Derald's on their breakfast sandwiches.
My sandwich was disappointing. It had enough avocado - once I could find it in the almost half cup of mayonnaise on the sandwich. The lettuce was iceberg lettuce and uninteresting. The tomato was okay. The bread was just white bread, fried in some kind of cheap vegetable oil. That made the sandwich much "heavier" and unpleasantly greasy. Like I said, I don't mind some grease, but this stuff tasted cheap and stale. After eating it, I felt kinda sick later in the day.
My girlfriend's burger had much less avocado. The patties were extremely thin and bland. The bun wasn't great either. For all they talk about fresh ingredients on the website, I am not seeing the quality reflected in the food.
The prices aren't cheap, either - $5 and up even for veggie sandwiches and up to $10 for burgers. Fries are extra - so we didn't get any, but I hadn't heard good things about them. Compare this to Black Dog, where you get an awesome burger and fries or other side for $8. Or Derald's, where the burgers are much cheaper and the veggies look more freshly sliced. If you must eat at a chain, try Culver's, even that's a much better deal, I think.
Since we got take-out I can't comment on the restaurant itself. I would still never get food from them again.
Edit: a note on this review. After it had been up for a little while, I was contacted via Yelp message by someone from Meatheads. They apologized profusely for my dissatisfaction and offered me a complementary meal in the future. I haven't taken them up on it - I'm still not in a huge hurry to go back - but they are trying to address unhappy reviews, and I think that's worth noting.
