"I had heard from friends that Kupel's is one of the very few kosher restaurants in Boston, so I was looking forward to trying their offerings. The bakery was bustling around lunch time on a Sunday. The menu is quite fun each sandwich is an MBTA stop name colored as its respective MBTA line. But, as I experienced, perhaps the fun naming scheme leads to mixups in making the orders. I ordered the Hynes, which is supposed to have egg salad, lox, tomato, and onion. I ended up having tuna salad in my bagel sandwich instead. The tuna salad was pretty unremarkable. I liked the lox (wish there was more of it), and the bagel was fine. When we went back to ask for the egg salad, they kindly gave us a small tub of egg salad as a replacement. However, I didn't enjoy the egg salad either it was not creamy and the egg white pieces were very tiny. I also got the elephant ear pastry, which had some weird discolored speckles on it. One bite that I had tasted like mold, so I ended up tossing it. I wouldn't try their pastries again it doesn't seem like they're guaranteed to be fresh. Overall, Kupel's is a very affordable option with a wide array of bagel sandwich combination options. Perhaps too many options...my friend's order got mixed up as well it didn't have any of the ingredients it was supposed to have and I've heard of more mixups in the past. I think Kupel's is a very important establishment that caters to many dietary restrictions at a reasonable price, and the employees are very nice about making up for wrong orders, but based on my experiences, I probably would not come back. I definitely do not recommend trying the pastries..."
