You might try Deep Creek restaurant and marina on (what else) Deep Creek.
As you enter the Magothy it will be the first creek on the port side of the channel. Food is really good but a bit pricy. Channel is well marked and should be deep enough. (I draw almost as much as you -- 6ft 1 in and I can get in). They have slips where you can tie up while you eat. Have also anchored behind Dobbins Island and taken the dinghy in but its sort of a long ride.
If you want to look Deep Creek Restaurant up believe its in Arnold, MD.
