I'm a minority in my family when I say 5 guys is OK but I tried it again when it opened up close to my home.
The likes:
Free peanuts - I'd never buy a bag of peanuts at the grocery store and sit at home and shell them but for some reason that's a draw in a burger joint for me.
Bag Fries - they purposefully give you bag fries (they have bag fries measuring bowls that they use to measure out the bag fries for each size of serving). This means the sizing is completely irrelevant when looking at the packaging. I think a large will feed like 4 people?! There still is something about bag fries that make them the best - why is that still the same when half the order is bag fries? I dunno.
The dislikes
For vegetarians, they don't have a veggie burger per say. The option is a grilled veggie sandwich with or without cheese.
The cheese. I love my cheese but this cheese is just too processed and melts into globs. I find it required to hold my veggies together (no patties for me - boo) but I dislike any bite with lots of it.
Overall I will go here sometimes. I know it's amazing for many people and I like it better than say burger king but it's not nearing the tops of any of my lists.
