Went to Mundo in Astoria (32nd, just south of Broadway) recently. We had a very nice time and were impressed (for the most part) by this little place.
First we had the cold soup special of the day, which was a cherry soup. It was interesting and a nice way to cool down. Then we tried the spinach dip which was excellent, creamy yet light with excellent warm pita to dip. Next we shared 3 appetizers, Argentinian empenadas, excellent, a great blend of spices, meat, olives and raisins inside of a soft flaky crust. Some kind of feta cheese rolled in phyllo and fried, also very good. The last appetizer was chicken with walnuts, which we did not really care for, it seemed almost like canned chicken and the garlic was kind of overpowering.
So overall we really enjoyed 4/5 of the dishes, and won't order the chicken again. But we definitely will be back to try more of their unique items. The service was very warm and welcoming, if a bit scattered at times. It was clear that they are still kind of new to all this, but in a good way. Only real gripe was that it was cash only. Otherwise a pleasant experience, I would reccomend. Oh, and its BYO (for now) so that is a plus in my book.
