In Texas, if you're planning to open a bar where patrons can consume alcohol on the premises, you'll likely need a Mixed Beverage Permit (MB). This permit allows businesses to sell distilled spirits, beer, wine, and mixed drinks for on-site consumption. It's worth noting that Texas has unique regulations and county-based restrictions for bar owners. Hence, always consult with the Texas Alcoholic Beverage Commission (TABC) to ensure you're obtaining the correct licenses and adhering to local regulations.
