M & M is an unbelievably consistent operation, as I have never been disappointed with the service or food here in the numerous occasions I have visited so far.  I have never walked in without being greeted politely, and having my muddy water (arnold palmer) and corbread cake served up immediately.  The fried chicken is always good, and I even tried the catfish the other day, excellent.  They do run out of sides on occasion, but no big deal as they have plenty of others.  An unexpected, amazing feat of service and quality from an unassuming joint off Charleston.
