Trostel’s Greenbriar remains a Johnston steakhouse favorite

A well-established local choice

Trostel’s Greenbriar carries one of the stronger public ratings among Johnston restaurants, with 4.7 stars from more than 1,000 Google reviews. The listing positions it as a moderately priced steakhouse, bar, banquet hall and event venue, and the reviews provided support its appeal for both ordinary dinners and family celebrations.

Longtime customers describe returning over many years, while first-time diners report finding it suitable for anniversaries, birthdays and meals on the road. That range matters. Greenbriar appears polished enough for an occasion without being limited to formal dining, and its broad service profile also makes it relevant for groups and catered events.

Prime rib leads the food praise

Prime rib is the clearest recurring recommendation. One anniversary diner called it the best prime rib they had eaten in a decade, emphasizing its tenderness. Another review praised a prime rib cut served with Gunpowder rub, alongside a ribeye. Those repeated positive references make the prime rib the safest starting point for a first visit.

The appetizers also attract attention, although no single starter repeats across the sample. Diners specifically mention shrimp Havarti, calamari and coconut shrimp, with the coconut shrimp receiving especially enthusiastic praise. One traveler also noted the presentation of the food and a selection of homemade sauces, including béarnaise and horseradish.

Taken together, the reviews suggest a steakhouse that gets its core meat dishes right while offering enough starters and accompaniments to build a more leisurely dinner.

Service is usually a strength

Service receives frequent, detailed praise. Reviewers describe servers as attentive, quick to take orders and capable of making birthdays or anniversaries feel memorable. A family celebrating a grandson’s birthday praised both the meal and the hospitality, while a couple traveling from Minnesota to Kansas appreciated service that kept dinner moving without making them feel rushed.

That consistency is a meaningful part of Greenbriar’s appeal. The restaurant is not being praised only for isolated dishes. Public feedback repeatedly connects the food with friendly welcomes, engaged servers and a sense that the staff handles celebrations well.

Busy nights can test the timing

The main caution comes from a Friday reservation when the dining room was full. Although the server greeted the party promptly, cocktails and wine reportedly took about 20 minutes, and appetizers arrived roughly 50 minutes after the reservation time. The sample review is truncated, so it does not provide the full outcome of that meal, but the timing details are clear enough to flag.

Reservations appear wise for peak periods, particularly when timing matters. Even with that caveat, the overall evidence remains notably positive. Greenbriar looks best suited to diners seeking prime rib, a traditional steakhouse dinner or a dependable setting for a family milestone.
