You should ask permission first if using a flash or video. I have noted the bars that are cigar friendly but sometimes you never know. If you wish to smoke it is always best to ask first. Max's on Broadway is since they sell many of the litter buggers. The Wharf rat Bar in Fells Point is not since they have many eating tables close to the bars.
Most visitors start out at the Inner Harbor.
The Water Taxi can take you to Fells Point and many other good places. You can pick up a taxi guide in the visitor's center. The guide is free and has one of the best maps to show you around. The water taxi guide also has the best map of Fells Point I have seen. For most of the city it's meters and pay lots.
