Going down Broadway heading north are a couple of very local Mexican places. The first you'd come to is a place called El Tejado, probably not walking distance but pretty close. Killer breakfast on the weekends. Further north a couple of miles is a spot called The Blue Bonnet. For years this has been one of the best Mexican places in town. If you get to feeling particularly home sick, there is a little place called Lucille's, some really good cajun stuff for breakfast and lunch, down by the Blue Bonnet off Broadway. There are some of the better pizza you'll find in Denver up and down Broadway, a couple of my favorite placeses are Pasquini's or Famous Pizza (about 1st Ave and Broadway).
Up and down Broadway there are all kinds of little Motels, some of those I can't say I'd send my dog to, but you could easily get a massage and a happy ending at those.
I was thinking, and for me the closest I could think of is a Merriott Suites on South Colorado Blvd. This place would also give you reasonably close access to a second room, Rack'em Cue Club. Rack'em recently got new owners and have redone the tables. I haven't had a chance to get over there, but I've heard it's a new attitude and good environment. There is also a Merriott Townplace Suites at about 6th Ave and Speer Blvd. This is between Felt and downtown, about 3 miles north of Felt just off Broadway.
When will you be coming? Usually at this time of year some hotel space is at a premium. My wife just reminded me it's yeee-haaa time here in Denver - The National Western Stock Show is in town. Lots of cowboys, and cowgirls (in cowgirl pants.... yum yum), they can be a fun crowd.
Good Mexican and some pretty good steakhouses. Enjoy!!!
