Many sushi restaurants offer fixed-price sets selected by the chef from the catch of the day. These are often graded as shō-chiku-bai (松竹梅), shō/matsu (, pine), chiku/take (, bamboo), and bai/ume (, plum), with matsu the most expensive and ume the cheapest.[citation needed] Sushi restaurants will often have private booth dining, where guests are asked to remove their shoes, leaving them outside the room; However, most sushi bars offer diners a casual experience with an open dining room concept.
