If he's talking the East side, dublin isn't a smart place to try to go. Its about 25-30 miles via the outerbelt, takes about 45 minutes or more (our freeway cops are very proud of their job ya'see) AND they are again working the north leg of 270 doing stuff... Dublin would-could be 2-3 hrs that way. lol
If you are East, Eastland Mall on South Hamilton road is the hot spot to find most all things in one cluster. Food, flicks, shopping.
East side, take 270 North pass thru the Gahanna area and go to the Easton exit. Newest and hottest shopping etc in the Columbus Area. Everything you can imagine is located in that general area. Gahanna poilces the freeway like all the other suburbs and they are pert serious about the numbers on the speed limit signs.
