Longtime chowhounders visiting from SFBA on Monday 7/3 and Tuesday 7/4. I'd hoped to take them to Pambiche/Karam/Bewon/Ya Hala or the likes (we are at Wildwood Sunday 7/2). Have discovered most mouth-watering spots closed on 4th weekend ... I'm new to Portland and a bit stressed, want very much to treat friends who have wined and dined me in SF to the best ethnic Portland has to offer. Any suggestions for those holiday nights?
