A contract is considered illegal when it involves activities that are against the law or public policy. In this scenario, the intoxicated buyer's offer does not constitute illegal activity; rather, the issue lies in the capacity to contract. Therefore, the contract is not illegal but rather subject to the buyer's ability to void it due to intoxication.

A void contract is one that is not legally enforceable from the moment it is created. While an intoxicated buyer may struggle to understand the implications of their actions, the contract is not automatically void. Instead, it remains valid until the intoxicated party decides to void it, making it voidable rather than void.

A unilateral contract is one in which only one party makes a promise or undertakes a performance, leaving the other party with no obligation unless they fulfill a condition. In this case, both the buyer and the sellers have obligations; thus, the contract does not fit the definition of a unilateral contract.
