Hi @frommtron,
I haven’t been to Ngu Binh at 5:45 - 6 p.m. on a Sunday, so I’ll let @attran99 @Ns1 @hppzz @JeetKuneBao chime in on wait times, but if it’s light, the food itself is quick to come out and very casual.
Maybe give them a call when you’re about 15 - 20 min out, to see how long the wait might be? Delicious food (Bun Bo Hue (Beef noodle Soup)).
Or I’d second Olive Tree as another option.
Good luck!
