The reading for this makes no sense at all. You'll have to learn it straight up, that is, unless you know the word おいしい already, which many people do as it's used in every other sentence in every Japanese variety show. If you don't know this word already, just think of yourself eating something delicious. It's so delicious it makes you mad, I have no idea why. You yell at the chef: "OI (おい). OI! WHY IS THIS SO DELICIOUS????"
Koichi and Viet secretly keep some good-tasting whiskey in the office.
I like trying little bits of many different tasty dishes.
Recently, a lot of pubs with delicious food have been opening in the Tofugu office.
