Spanish mini-sandwich chain 100 Montaditos (1776 Wilson Blvd) is opening its first Arlington location on Monday (March 31) in Rosslyn.

In honor of the grand opening, customers on Monday will be treated to a free “montadito,” a spanish sandwich with ingredients like chorizo and serrano ham, and a drink. The montaditos typically cost between $1 and $3.

If customers can’t make it on Monday — or want to avoid the lines free food usually attracts — the restaurant is offering a buy two, get one free deal until April 6, according to the Rosslyn Business Improvement District.

In addition to the montaditos, the restaurant offers beer and sangria, with pitchers of the fruity wine drink and domestic beer offered for $8.
