Saturday evening with non-drinking age teens in Baltimore?

We'll be spending the weekend of 2/5/2011 in Baltimore with teens that are not of drinking age. Most of the tourist attractions (aquarium, science center, etc.) close by 5 or 6PM on Saturday. Does anyone have suggestions for teen-friendly activities on a Saturday night? (We'll be staying near the convention center in the Inner Harbor area). Thanks!Saturday evening with non-drinking age teens in Baltimore?
Go to Dick's last resort for dinner...
