South Congress is getting a fresh late-night sugar fix. Insomnia Cookies is moving into the St. Elmo stretch with a new shop that will sling warm-baked cookies and offer late-night delivery out of the Bishop Momo development. State filings and commercial listings show the chain has locked in a ground-floor retail space at 4341 S Congress Ave in Bishop Momo, with work already underway, although the company has not yet shared a formal opening date or grand-opening details.
State Filing Points To April Finish
According to WhatNow, a Texas filing tied to the project pegs April 1, 2026 as the projected completion date and estimates the interior buildout at roughly $240,000. That same report notes that no official opening timeline has been announced.
What The New Shop Will Sell
On the menu, Insomnia sticks to its greatest hits: classic cookies like chocolate chunk, snickerdoodle, sugar and oatmeal raisin, plus larger "deluxe" cookies, ice-cream cookiewiches, cookie cakes and other sweets, as listed on the menu from Insomnia Cookies. The brand is known for late-night delivery and typically offers vegan and gluten-free options at select locations, so the new South Congress shop is likely to follow suit with a mix of pickup and delivery service.
Where On SoCo It Will Sit
The new store is slated for a ground-level retail unit in the Bishop Momo mixed-use development, facing South Congress near the St. Elmo Public Market, a stretch already lined with restaurants and shops. A listing on LoopNet confirms a ground-floor retail space at 4341 S Congress and touts high pedestrian and vehicle traffic along the corridor, which helps explain why a delivery-focused concept would zero in on this spot.
What To Watch For Next
Insomnia has not yet shared any Austin-specific grand-opening details for the South Congress location. When the chain does open new stores, it often rolls out opening-week deals and free classic-cookie giveaways. The company has been expanding quickly across the U.S. in recent years, a growth push outlined in a corporate press release from PR Newswire, suggesting the South Congress shop is one more step in a broader national rollout.
