Got deluxe w/ gluten free bun thru GrubHub so didn't make direct contact w/ staff. asked them to mind cross-contamination, ordered fries and asked them to remove them from order if no dedicated GF fryer -- they removed them so I'm assuming the fryer isn't GF.
Writing about an hour after my first bite and not feeling anything. will update review if I do.
burger was distinctly "just ok" but enough to satisfy my burger lust :p
Very polite staff members. Burger bun was soft and pretty good. burger patty (smallest size) was basic, similar to a McDonald's hamburger patty.
