Thanksgiving in Volcano, HI?
Kilauea Lodge is a good bet, porbably your only good restaurant option. However, there is a great caterer in the area, who'se name escapes me, but many of the B+B's can contact them for a gourmet lunch or dinner delivered to you...not cheap, but very romantic and delicious. The same folks usually show up at the Volcano Farmer's Market on Sunday mornings...get there early, as they start to sell out of the good stuff by 8 am. The farmer's market is a must stop anyway, and that is a big weekend, with the famous Studio Art Sales all over the area.
If your lodgings can't supply the name of the caterers, try asking Peter and Kathleen Golden at Volcano Rainforest Retreat...http://www.volcanoretreat.com/. Best to reserve ahead for either caterer or Lodge...that is a busy busy time for that little village.
