About No. 423 Smokehouse
No. 423 Smokehouse in Petersburg, Indiana is a Pike County BBQ restaurant that happens to produce a breaded pork tenderloin sandwich that reviewers call giant, ginormous, and genuinely ridiculously large relative to the bun. For a smokehouse that leads with brisket, ribs, and pulled pork, that is a meaningful tenderloin achievement.
The pork is cooked to perfection according to multiple reviewers, with great atmosphere and staff that make the meal worth the trip into Pike County. The size is the lead detail: the loin-to-bun ratio is notable enough that it gets called out specifically, and the flavor backs up the portion. Petersburg already has Caddyshack a couple miles away making a case that size is not the whole story, but No. 423 Smokehouse is making the opposite argument from the other end of E Illinois Street.
Petersburg is the Pike County seat in southwestern Indiana on US-61, about 30 miles north of Evansville. The smokehouse program gives No. 423 a dual identity: serious BBQ destination and legitimate tenderloin stop, which is a combination that is rare enough to be worth knowing about.
For anyone routing through Pike County on US-61 or building a southwestern Indiana tenderloin and BBQ itinerary, No. 423 Smokehouse at 804 E Illinois St in Petersburg is the stop. Get the tenderloin, but also look at the brisket.
