I was working in Billings and wound up staying at the Hampton Inn which is across the parking lot. I didn't have a car so I wound up eating at Fiddler's Green four nights in a row.
Fiddler's Green is a sports bar & grill plus casino all in one. They have a nice variety of tap beers and a full bar. They had a different bartender every night I was there; all were pretty young ladies. I'd say Tiffany was my favorite, she had the most outgoing & friendly personality. However, none of the bartenders were bad, just my personal preference.
The house special is clearly the Pork Chop Sandwich (photo attached) and its huge. The picture I posted is the smallest one I saw all week. I also tried the hot pastrami sandwich which wasn't bad but clearly not the absolute best pastrami.
Prices are very reasonable, I had one or two cocktails & one or two draft beers every night, combined with a sandwich and think my bills (with 20% tip) ran between $26-$35. Try the Dragon's Breath dark wheat beer, very nice. They also have Guinness on tap which is always a plus.
I have no complaints about Fiddler's Green, its a good neighborhood bar & grill.
