A friend and I made it to Apsara this evening, which made a nice halfway stop between Maine and Western Mass. Big thank you to DT and Applehome for the help/recommendations.
I really wanted to like this place, but overall I thought it was just "pretty good." Fresh spring rolls were very good, perhaps the highlight. They were large and filled with shrimp, noodles, vegetables, mint, etc. and served with a nice peanut/fish/sweet/sour dipping sauce. We ordered the catfish, which was good but not great. The fish was fried and crispy, but had very little flavor and was a bit too greasy. The green mango salad served with it was very good however, and mixing the two in the same bite made things pretty good. Lastly we shared one lok lak combination rice plate...the serving was a bit small but the caramelized beef was very good.
Once again (see my Portland Maine post) we were the only people seated in the restaurant, although I was surprised that the place was so large! I probably wouldn't ever go there again, especially since I want to continue to explore Lowell's SE Asian options (not that I'll be in Lowell again any time soon)...as far as Cambodian food goes though, I have had much better experiences at Floating Rock in Revere, MA. Anyway, I seriously do appreciate the chowhound advice, it's fun to drag friends to random cities to eat in new restaurants, and fellow chowhounds makes this all the more possible.
