On the other hand, if all you want is cheap tables, off-Strip is your best bet, such as on Fremont Street (which is still a tourist area), including El Cortez. If it’s your first time in Vegas you should visit a few different ones to see which one works best for you, since each one has a different atmosphere (see paragraphs below).
In general, the choice of which Vegas casinos is best for you clearly depends on what you are looking for, if it’s the atmosphere, or the elegance, or the number of slot machines (and how modern and fun they are), or how ‘loose’ the slots are, or the type of tables it offers, or even the type of crowd.
