I am not a mac 'n cheese expert by any means, I am however trying to replicate an experience of "chipotle mac and cheese" that changed my life. The mac and cheese at Flo's was sadly underwhelming. No sauce to speak of, just naked noodles covered with a smattering of various cheeses, that were a bit bitter actually. The accompanying greens were standard "green salad" fare, and I personally wasn't wild about the house dressing. I was nervous about ordering a substitute as per the warnings of previous patrons; "any substitutions are EXTRA".
As far as service goes, there were very few other patrons in the diner so my expectation was speedy, it turned out to be a little more on the slow side. Nothing to take issue with, but then again nothing really to go back for. Honestly even as I am writing this the I am remembering feeling very underwhelmed. My companions meal was standard fare, and tasted as such.
Bottom line...there are at least a dozen other places in this area where you will eat better for about the same price.
