Houston-born Tex-Mex staple Los Tios, known for its puffy queso and house frozen margarita, is headed for Alamo Heights this spring. Adair Concepts is converting the former La Madeleine at 4820 Broadway into the brand’s first Greater San Antonio outpost, bringing a full-service Tex-Mex restaurant and bar to a 5,500-square-foot space that has anchored the corridor for decades.
According to WhatNow, Adair Concepts has filed plans to overhaul the shuttered La Madeleine building and is still working through construction and permitting. A state permit had the project penciled in for completion last November, but upgrades have continued, and WhatNow reports that the roughly 5,500-square-foot dining room is now slated to debut this spring.
State filings cited by the San Antonio Current put the renovation tab at about $531,000 and listed a June-to-November construction window. The Current also notes that Los Tios joined the Adair family portfolio in 2000 and credits the restaurant with introducing Houston to the frozen margarita in 1975.

The long-running frozen margarita remains a staple as well. The site traces Los Tios back to the Garbett family in 1970 and notes that the brand became part of the Adair portfolio in 2000.
