Euro Delicacies, conveniently located in Southwest Las Vegas, has been my go-to spot for Eastern and Central European groceries for awhile now. It's close to my house and provides a good offering of various Slavic and German foods. New is a small produce section and additional cases of frozen foods containing cevapi and a plethora of various cuts of meat. I have to give Euro Delicacies at least 4 stars because they carry my favorite mineral water -- Naleczowianka. Any place that carries random Polish sparkling water is great in my book.
Also, unlike other European grocers in Las Vegas, Euro Delicacies' packaged food tastes fresh, like they frequently replenish the stock. I hate that "I've-been-sitting-on-the-shelf- for-two-years" taste. They also have a large selection of pasztet (country-style pate) and several varieties of ajvar (roasted red pepper spread), which is delicious as a sandwich spread. I'm excited to spread some ajvar on the bread baked at Natalia's Bakery which recently opened next door.
I only wish they had a better soup selection. Most of it seems to be German and not a barszcz czerwony or krupnik soup packet to be seen. Oh well, no one is perfect.
