When you get tired of lucullan,epicurean,gourmand, etc., try
Abligurition
(Ab*lig`u*ri"tion) n. [L. abligurito, fr. abligurire to spend in luxurious indulgence; ab + ligurire to be lickerish, dainty, fr. lingere to lick.] Prodigal expense for food. [Obs.] Bailey.

Incidentally, "lickerish" is not a compliment either.
