Dates you say? Well going to the movies is always an easy option.
Assuming your in college... there are usually places such as conservatories or planetariums that can be fun and romantic, going to campus events in general as dates are usually very inexpensive.
If your past college, you can try going to a new restaurants every week or two, it doesn't even have to be an expensive one (you can do the research online on price ranges...), just getting out at all makes for a fun date. Even if the restaurant is not high quality, you can still go that extra effort to dress up.
Hope that helped
