2. **Salsas and Curtido**: Complement your pupusas with their homemade salsas and curtido (pickled cabbage), which add great flavor and texture.

3. **Be Prepared for Crowds**: As a popular spot, it can get busy, especially during lunch and dinner hours. Arriving early can help you avoid long waits.

4. **Cash-Only Policy**: Check if they accept card payments beforehand, as many food stands operate on a cash-only basis.

5. **Explore Other Options**: Besides pupusas, try their tamales and other Salvadoran staples for a well-rounded experience.

6. **Check Social Media**: Follow their social media for specials or pop-up events.
