Ext Lettuce

I'd be happy to help you learn about exotic lettuce found in restaurants in the USA!

The exotic lettuce you're referring to is likely known as "Ext lettuce" (not "Ex-t" as it's incorrectly spelled). Ext lettuce is not a widely known type of lettuce, and I'm assuming it's a mistake in the name. However, I'll provide information on various types of lettuce commonly found in restaurants in the USA:

1. Romaine Lettuce: This crisp, slightly bitter lettuce is widely used in salads and sandwiches. It's characterized by its distinctive oval shape and slightly sweet flavor.

2. Iceberg Lettuce: Known for its crisp leaves and mild flavor, Iceberg lettuce is commonly used in salads and as a wrap. It has a pale yellow color and a crunchy texture.

3. Boston Lettuce: Often used in salads and sandwiches, Boston lettuce has a delicate flavor, soft leaves, and a mild bitterness. It's typically available in three sections: outer leaves, inner leaves, and the tender center leaves.

4. Butter Lettuce: Also known as Butterhead or Boston Bibb, this type of lettuce has a soft, tender texture and a mild flavor. It's often used in salads and sandwiches and is popular for its delicate, buttery leaves.

If you could provide more information or context about the "Ext lettuce" you're referring to, I'd be happy to try and help you identify it. Alternatively, if you're looking for a specific type of lettuce or would like more information on the types listed above, feel free to ask!
