I recommend the European Outdoor Chef City Grill

This is a little, lightweight portable gas grill with the features, function and power of a full sized grill. The internal engineering centers around a pair of baffles (for lack of a better word) that allow you to focus the heat or distribute it. This gives you heating versatility in a single burner design. Under normal grilling you actually get a hot zone around the outside so you have lots of searing space and since you can reach over 500 degrees F. with this unit you can actually sear a steak. This is an excellent portable grill as well as a great apartment grill.
