If you like art go to Western Ave Studios. Lots of awesome art and Navigation brewery is downstairs. Also Mill No 5 in downtown lowell has alot of cool shops and stores and an old-school movie theater. Lots of amazing food in downtown lowell as well if your into Cambodian, Vietnamese and Thai food. If you like Pho I recommend Phnom Penh on Westford St. The best oxtail Pho in the city.
