I saw it on Google Alerts: Park Slope. It was on Daily Slope. Rumor has it that the old Tea Lounge on 10th Street and Seventh Avenue is going to be a Vietnamese sandwich shop, the first in Park Slope.

It looks like something will be moving into the Old Tea Lounge location on 7th Avenue and 10th Street soon. Men have been seen working on the space the past week. A neighbor informed me this morning that she had asked them what was coming in and they told her a Vietnamese Sandwich Shop.

So what is a Vietnamese sandwich? Here’s Wikipedia on the subject:

Bánh mì or bánh mỳ (pronounced /ˈbʌn mi/ in English and IPA: [ʔɓɐ̌ːɲ mì]] in Vietnamese) is a Vietnamese baguette made with wheat and rice flour, as well as a type of sandwich traditionally made with this type of baguette.^[1] The sandwich is made up of thinly sliced pickled carrots and daikon, onions, cucumbers, cilantro, jalapeño peppers and meat or tofu. Popular bánh mì fillings include roasted or grilled pork, Vietnamese Ham, paté, mayonnaise, chicken, and head cheese.
Most Banh Mi sandwiches contain a Vietnamese mayonnaise-like spread
that is a mixture of egg yolk, cooking oil/butter, and sometimes spices.

Bánh mì is generally served in small shops and at some phở noodle eateries. Bánh mì shops can be found in many countries, especially in areas with a Vietnamese immigrant community. The contrasting flavors and textures of the sandwich — as well as its relatively low cost — make it a popular dish.
